My inventionl relates to typewriting machines', and more particularly toimprovements in tabulating mechanism therefor.

In a tabulating mechanism of the column selecting type, it is customaryto provide a plurality of column stops adjustably mounted in spacedrelationship longitudinally of the carriage, and these column stopsgenerally differ from each other in that each is provided with a contactportion which is so disposed as to travel in a different path from theContact portion of any of lthe'other column stops. The cooperating orcolumn selecting stops are usually key controlled `and mounted on theframe of the machine at l different heights or positions correspondingto the different paths of travel of the contact portions of the columnstops on the carriage, so that each column selecting stop coacts withonly one of the column stops to arrest the carriage at a given columnarfield.

In certain typewriting machines, such as the No. 10 Remington Noiselessand the No. 11=Rem` ington machines, the carriage in its entirety has asubstantially vertical case shifting movement relative to the frame ofthe machine. In such constructions, it will be clear that the verticalcase shifting movement of the column stopswith the carriage willinterfere with the proper selective cooperation between the differentvertically spaced contact portions thereof and the column selectingstops carried by the frame of the machine.

The main purpose of my invention, generally stated, is toI overcomethese and other difliculties and provide improved, highly efcient andreliable tabulating mechanism in a typewriting machine of the typewherein the carriage in its entirety has a case shifting movement.

To the above and other ends which will hereinafter appear', my inventionconsists in the features of construction, arrangements of parts andcombinations of devices set forth in the following -Fig..3 is afragmentary top plan view of the I rear portion of the machine shown inFig. 1, the view showing certain parts broken away and other partsomitted.

I have shown my invention embodied in the A present instance in a No. 10Remington Noiseless machine in which the features of the presentinvention may be readily incorporated with but few changes in theexisting structure. However, it is to be understood that my invention isnot restricted to embodiment in such machine but may be employed invarious other types of typewriting and like machines wherever foundavailable.

I have shown in the accompanying drawings only so much of the usualconstruction of the No. 10 Remington Noiseless machine as isnecesopposite ends of a main carriage supporting rail I8, The carriageis mounted for longitudinal letter space travel from side to side of themachine on a case shiftable member or guide rail f 20 by crossedanti-friction rollers 2l received in oppositely disposed raceways 22 insaid guide rail and companionraceways 23 in the sides of the carriagesupporting rail I8.

The entire carriage is mounted for substantially vertical case shiftingmovement by a case shifting rock shaft 25 pivotally supported at 26 (seeFig. 3) on the frame of the machine. Thus, depending lugs S6 on theguide rail 20 are pivotally connected at 3| to companion crank arms 32carried by the rock shaft 25. The elevated or upper case position of thecarriage and case shifting mechanism therefor is shown by the solidlines in Figs. 1 and 2 and in the last mentioned figure the. `dottedlines illustrate the lower case position of some of' the parts.

Referring more particularly to Fig. 2, it will be understood that thecase shifting movement of the carriage is effected by rocking theslr-aft, r(2.5 through the usual case shift operating mechanismincluding a toggle crank Sill pivote'cl at 361 to an arm 37 extendingforwardly from the rock shaft 25. The crank 35 is pivotally connected at38 to a link 39 which in tilllLiS pivotally con-v nected at lil to therear end of an arm 4l pivoted at 42 to the side plate l!) of themachine-frame. The forward end of the arm ill. is' connected at 43 to acompressible link crgn-nectionv which is of the usual construction toafford.v a limi-ted amount of resilient eompressibi-lity and has beendesignated as a whole bythe reference numeral lili in Fig.Y 2. TheYlower end of thev link. connection 2d is connected at 4,5- to a crankarm t5 extending rearwardly from a key lever operated rock shaft 41.which is pivotally mounted at its end portions by means, not shown,tothe side plates I0 of the machine frame. Y

The usual case shifting key levers 48 are operatfvely connected, one atMl, to the respective crank arms 46 at the endportions of the rock shaft4:1, these crank arm-s being somewhat alike and each of the key levers138. carries a case shift key El). at the forward end thereof. The usualcase shift locking mechanism is provided on each of the oase shift keylevers 48, and this mechanism includes a shirt, lock key 52 carried byan armv 53 pivotally mounted at 5.4. upon the associated. lever- 48 andoperating against, the force of a contractile spring 55. Each arm 5.3:coacts in theusual mannerv with a latch member 5,6` pivoted at 5l to thecompanion lever 43 andl each latch member 5.5. operates. on anassociated latch plate 58` mounted at 5,9-to. the sidev plate lil, andthus acts toreleasably hold the levers 431m their depressed or uppercase position in the usual manner.

The illustrated upper case position of the various case shifted parts islimited by an adinstable stop screw 6i) carried by the arm 3l and`engageable with thehead of a screw 6i threaded into the cross member l2of the machine frarnaV The lower case positionl illustrated by*Ithedotted lines in Fi-g. 2 is limited by the IlSllal: toggle stopmechanism including a crank 22 pivotallymounted at 6,3 to a side platetil and pivotally con-`V nected at 64 tol a. depending of the togglecrank 35. Aforwardly'extending arm of thebell cranklever 62 is shifted;by a movement of the case shifted parts to their lowercase position intoengagement with the head of an adjustablestop screw 65 also carried by aside platev lli. A contractile spring 66 is provided, between the bellcrank lever 62- and thefhead of the pivot screw-42.`

Referring to- Fig. 3, it maybe seen that the carriage.` is impelled in aletter feed direction bythe usual spring drum 10 carried by a bracket 7|mounted-on-the`A crossvmember` l2 of theframe of the machine. A pull.band '12eXtends from the sprlgi 'l'.4 to. accnnecting bracketV 'i3carriedfby the; richt-handbagage end-.Plate Vif- As may be seen in Figs.1 and 9, the carriage movement in the letter fed direction is normallycontrolled by theusual form of escapement devices including a releasablefeed rack 15 pivotally mounted on the carriage supporting rail i 8 tonormally engage a feed pinion 16 fixedly secured at the upper end of asubstantially vertically disposed feed shaft 17, feed shaft 'Vl isrotativelyr supportedAbyV av socket bearing 'f8 (see Fig. 3) pivotallymounted at 'IS in a bracket 8G secured to the carriage rail 20 at '8LAs. best: shown in Fig. 9, an escapement wheel 82 is operativelyconnected near the lower end oi the feed shaftl-'l to rotate therewithand is rotative'lyA supported` by the usual tabulating brake drum 33 ina bracket 84 mounted at 85y on the cross; member l2 of the machineframe. The connection between the feed shaft Ti and the escapement wheeli2y is herein shown as comprising, the usualanti-friction bearing lballs86 received' in oppositely disposed longitudinal grooves` or ways in thehub portionof the escapement wheel 82 and in corresponding grooves orways in the escapement feed shaft 11.

The :upper end of the The usual form of dog rocker assemblyrisferng`ployedto cooperate with the escapement wheel 82, and comprises in therpresent instance a dog rocker 8.8 having downr turned lateral endportions recessed to receive coned ends of pivot sea;

screws 89A carried by respective Vspaced arms .98" i extendingrearwardly and downwardly from the bracket 84. A Aforwardly extending.arm 9i. of the dog rocker 8 8 carriesonthe upper side, thereof a holdingdog 92 pivotally mounted'thereon at 93 and biased ,toits normal positionby a.'

spring S4 tov engage the teeth of the escapement wheel 8,2. 'I'heholding dog 92 is also mounted on the pivot 93 for a slight slidingmovement against the force of a spring 95.

A stepping dog 96 which is normally out of engagement with the teeth ofthe escapement wheel 32 is pivoted at 91'- on the lower side of thearm9| of the dog rocker to receive a movement against the force of thesame spring 94 thatis also connected toy the holding: dog 9-2. Themove.- ment,v ofthe stepping dog 96 against the fo-rce of the spring 94is limited by a stop arm 98 which,

entersI a bifurcation in they tail of the stepping dog lili.V The stoparm 98 is mounted by a pivot (not shown) which is adjustably secured toa rearwardly extending portion of the dog rocker` The dog rocker 88isbiased to its normal position by a spring 99 to engage a stop screw100 with theI edge ofthe associated bracket 90 and thereby limit the`return movement of the dog rocker to the normal position. The dogrocker is rocked about the pivot screws 89 upon the actuation of any oneofthe printing keys or the space bar by the usual means, not shown.

I-n order to release the carriage for tabulating,

the mechanism` usually employed in the No. 10v

Remington Noiseless machine is used in the present instance to releasethe holding dog 92 from the teethof the escapement wheel 82 and also toapply the usual friction brake to the brake drum 83. 'I'hus uponreference to Figs. l and 9, it will be seen that in the presentinstance, a bell crank lever H35 is pivotally mounted at N36 on adepending bracket i'l which is xedly attached to the cross member I3ofthe machine frame by thesame screws that are provided to hold thebracket 84. Referring to Fig. 9, it will be-clear that Whentherearwardlyextending arm of the bell crank` lever |05 is raised, the upright armthereof operates against the tail piece |08 of the holding dog 92 torock said dog out of engagement with the teeth of the escapement wheel82 and thereby free the carriage from control of the escapementmechanism for movement from right to left under the power exerted by thespring drum 10. v

The friction braking means, which is provided to retard the movement ofthe carriage when the holding dog 92 is thus released, comprises africtional brake member H0 pivotally mounted at IH on the bracket 84. Aleaf spring H2 attached to the brake member H0 at H3 coacts withanadjustable stop screw H4 threaded into the bracket 84 and is arranged topress the brake member Hi) towards the brake drum 83 and to a positionwhere a shoe portion Ha engages the periphery of the brake drum.

The application of the braking member H0 at a Vtabulating operation iseffected in the following manner. A contractile spring H6 is connectedto the rearwardly directed arm of the bell crank lever |05 and to across member H1 of the rear cross plate of machine frame, and thetension of this spring is suicient to overcome the tension of the springH2 and normally hold the brake member H0 out of effective engagementwith the brake drum 83. This is brought about by the engagement of theupright arm of the bell crank lever |05 with an adjustable contact screwH8 carried by an extension H9 of the brake member H0. It will now beunderstood that when the rearwardly directed arm of the bell crank lever|05 is operated upwardly during a tabulating operation, as will behereinafter more fully described, the holding dog 92 will be releasedfrom the teeth of the escapement wheel 82 and the brake member H0 willbe spring `.pressed into effective engagement with the brake drum 83. v

Although I have described in detail the case shifting mechanism, thecarriage escapement mechanism and the mechanism by which the carriage isreleased from control of the escapement mechanism on the actuation ofthe tabulator which are ordinarily, employed in the No.

10 Remington Noiseless machine, it should bev understood that so far asthe present invention .is concerned any suitable devices may be employedin lieu of these parts.

The tabulating mechanism in the present instance is of the columnselecting type and includes the usual arrangement of a plurality ofcolumn stops adjustably mounted in spaced relationship longitudinally ofthe carriage and each provided with a contact portion which isdifferently disposed than the contact portion of all of the other columnstops so that each contact portion travels in a different path from allof the others. The column stops cooperate with key controlled columnselecting stops each disposed to coact with onlyone of the column stops.

In the present type of machine, wherein the ,entire carriage, includingthe column stops, has a case shifting movement, I propose to mount thecooperative column selecting stops to receive a case shifting movementwith the carriage in order to retain the proper selective cooperaationbetween the column selecting stops and the respective column stops. Ifurther propose, nevertheless, to provide individual key operatedcontrolling means mounted on the frame of the machine for each of thecolumn selecting stops, which controlling means are operative to controlthe companion column selecting stop regardless of the case shiftedposition thereof. Thus, the carriage carries a rack or column stop bar|25 mounted longitudinally between the upper rear ends of the carriageend plates |1 and adjustably secured thereto. As may be seen in Fig. 3,a similar mounting means is provided for each end of the stop bar |25,one of which mounting means will be described with reference to Fig. '1,it being understood that such description will apply to both.

The upper and rearward portion of each carriage end plate |1 is providedwith a'boss |21 having a screw |23 threaded therein., The inwardlyprotruding end of the screw |23 passes through'a fore and afthorizontally disposed slot |28a in an L-shapedbracket |29 and a nut |30is threaded on the screw |28 to retain the bracket |20 in place againstthe usual paper table supporting bracket |3|. This last mentionedbracket also has an opening receiving freely therethrough the screw |28and bearing against the inside surface of the boss |21. The other armofthe bracket |29 also has a horizontally disposed slotted opening thatextends inthe direction of the 'length of the column stop bar andreceives the stem of a headed screw |32 threaded into an opening in thestop bar |25.

The outwardly protruding end of the screw |28 passes through a spacingwasher |33 and through `a horizontally disposed fore and aft slot in asecond Lshaped bracket |34, and the bracket |34 is held in place by anut |35 threaded on the screw |28 and bearing against the outsidesurface of the washer |33. The other arm of the bracket |34 is alsoprovided with a slotted opening that receives the stern of a headedscrew |35 threaded into an opening in the stop bar |25.

It will now be clear that the horizontal slots in the brackets |20 and|34 afford 'a slight amount of horizontal adjustment of the rack bar |25relative to the carriage end plate l1, and likewise the slots receivingthese screws |32 and |36 respectively afford a slight amount oflongitudinal adjustment of the rack bar |25 relative to the end plate|1. In order to facilitate this longitudinal adjustment of the stopbar|25 .and to hold it against accidental displacement from its adjustedposition, an adjusting screw |31 is provided which is threaded through atapped lopening in the bracket |34 and engages at its inner end an endof the stop bar |25.

Referring to Fig. 3, it will be seen that the stop bar |25 is providedwith teeth |33 in both the front and rear vertical faces thereof whichare spaced a letter space distance apart. The stop bar |25 carries inthe interdental spaces thereof a plurality of tabulator or column stopseach designated as a whole by the reference numeral |40. There are liveof such stops emp-loyed in the present instance which may be adjusted tothe desired spaced relationship along the bar |25.

These column stops |40 are all similar in construction, except ashereinafter pointed out. Each stop, as may be seen in Fig. 5, comprisesa generally U`shaped piece |4| adapted to straddle or t over the stopbar |25, and each of the vertical. legs of the U-shaped piece |4| isprovided with two webs Uilab which are spaced to fit companioninterdental spaces in the stop bar |25. A finger piece |42 is riveted inan opening in the'top of the U-shaped piece |4|, and the downwardlyYprojecting endt of' the finger piece` L42v` isr adapted'` to engageL theupper surface of the stop bar |25 and thereby accurately determine thevertical position of the column stop |66y on the stop bar |25.

The column stops M are in the present instancev employed for columnselecting and are respectively numbered i, Z, 3, d and 5 as may be seenin Fig. 3 and are arranged in this order from left to right. Each of thestops |40 is accordingly provided with a lug or contact portion |63which extends rearwardly from the rear Vertical leg of the U-shapedpiece Ml. However, the contact portion |133 of each of the stops |40 isspaced at a relatively different point along the rear vertical surfaceof the piece |f||. That is, theconta'ct portion |63 von the extremeleft-hand stop i is at the top of the piece |61 while the contactportion |03 on the extreme right-hand column stop 5 is at the bottom ofthe piece |12| and the contact portions of the intermediate stops arespacedv at relatively different intermediate levels. Therefore, theAcontact portion |03' on each. column stopA travels in a different pathfrom the paths of the contact portions on the remaining stops.

As previously stated, the column selecting stops coacting with the stops|60 on the carriage are mounted for case shifting movement with thecarriage. As best shown in Figs. 1 and 4, the column selecting stops andcertain of the controlling means therefor are, in the present instance,mounted in a frame that receives a case shifting movement with thecarriage and is received between and above two parallel guide membersorvertical webs |66 and i6? which are integral with and extend rearwardand upward from the cross member i2 of the machine frame. A fixed guideplate |68 similar to that employed in Remington Noiseless machines toresist the pressure of the type bars on the platen and carriage isfixedly secured to the members |56 and |61 by headed screws |49 that arethreaded into tapped openings in inwardly extending portions !llla andUlla of the webs |66 and |47 respectively.

', rail |56.

This guide plate |68 cooperates with the usual means that coact with acarriage thrust rail which is secured at its opposite end portion byscrews |5| to the respective carriage end plates l. Thus, as may be seenin Figs. 5 and 6, a bracket |52 extends beneath the thrust rail |50 andcarries two spaced rollers |53' pivotally mounted thereon to engage thefront edge of the Secured to the front end portion of the bracket |52 isa retaining strip |56 having U-shaped lugs |54a which embrace the frontedge portion of the rail |50. A down turned arm or foot piece at therear of the bracket `I5? is apertured to receive the stem of a headedscrew |55 extending through an opening therein and through an elongatedVertical slot llla in the guide plate M2. The stem of the screw |55 alsopasses through an opening in a retaining strip |56 which is securedthereon by a nut |57 threaded on a reduced diameter end portion of thescrew |55.

The retaining strip |56 is sufficiently wide to overlie the walls of thevertical slot in the guide plate M3, as may be seen in Fig. 4, and anarrower upper end portion |56a of the retaining strip is bent forwardto extend through the slot Nga in the guide plate |48 and to contactwithout binding the upper surface of the thrust rail |50. The rear edgeof the thrust rail |50 engages' the guideplate |548v to` resist anyrearwardr displacement of the carriage, and the rollersl |53L byengagingl the forward edge of the thrust rail?.

have a corresponding case shifting movement permitted by the verticalslot Illa in the guide |68 but these parts except. the thrust railV |50,are retained against a letter space feed movement byy the walls of thisslot Hwa in the guideV plate.

In the present instance, the guide plate |48 is ymodiiied to carry amounting means or guide for a case shifting carrier or frame in whichthe column selecting stops and certain of the actuating devices thereforare mounted. Thus, referring to Fig. 8, it may be seen that a carrierguide member or plate 60 is provided in the rear of the guide plate |128and disposed substantially parallel therewith and is accordinglydisposed in alignment with the substantially ver@ tical case shiftingmovement of the carriage;Y

The plate |6015 held in this spaced relation at the rear of the guideplate |68' by headed screws |6| (Figs. 6 and 8) which pass throughopenings in the upper end of the plate |60 and through! openings in, aninterposed part of a guide shoe |62 andare threaded into the guide plate|46.

The lower end of the plate |60 is retained in asimilar -manner by screws|63 which pass through openings in the lower end! thereof and throughopenings in a spacer |661 and the foot piece of a U -shaped bracketl andare threaded into open'- ings in the lower portion of the guide plate|48. The spacer |64 together with the bracket |65 have a combinedthickness which is equal to that f of the guide shoe |62V so that the.plate 60 is held in exact parallel relation with the guide plate 48. Thefunction of the guide shoe |62 and bracket |65 will be described indetail later.

The width of the guide plate |6`0`is sufficient to overlap the spacer|64 and the base portion ofthe guide shoe |62, and inr the presentinstance this overlapping edge portion of the guide plate forms a guidefor the case shifting frame of the column selecting stops. Said frame inthe present instance includes two side plates |66 and |6'l` (Figs. 6 and8) having longitudinal grooves receiving the overlying edge portions ofthe plate |66'. The plates |66 and |61 are connected by a separatingplate |68 and by screws |69. The connected plates |66 and |61 are thusguided for movement' along the plate |60 in exact alignment with thecase shifting movement of the carriage.

In the present instance, a substantially horizontally disposed box-likehousing is provided above the ends of the side plates |66 and |61 forenclosing the column selecting stops which coact with the column stopshill on the carriage. Thus referring to Figs. 4, 5 and'6, it may be seenthat a three sided housing open at the front thereof is mounted by meansof an angle bracket 1| (see Fig. li) upon the side plate |66, the anglebracket `lll being secured to housing- |7|0 by respective screws |14threaded into openings in lthe rear edges thereof.

The frame for the column selecting stops thus far described, includingthe end plates |66, |61 and the housing |10 is connected for caseshifting movement, in the present instance with the case shiftingcarriage guide rail 20. Referring to Figs. 4 and 5, it may be seen thatthis connection is provided by a rearwardly extending arm |15 having alaterally bent portion thereof xedly secured to the lower surface of thecarriage guide rail 20 by screws |16. The rear end of the arm |15 isxedly though adjustably secured by a bolt |11 to the lower end of aconnecting link |18 which is secured at its upper end by a screw |19 tothe side plate |66. The bolt |11 is received in a substantially verticalslot in the arm |18 and is held in its adjusted position therein by aclamping nut |114, whereby the arms |15 and link |18 may be xedlyconnected at relatively different positions in order to adjust the caseshifted positions of the frame which carries the vcolumn selectingstops.

As shown in Figs. 4, 5 and 6 a plurality of pivoted horizontallydisposed, column selecting stops |80 'are mounted in spaced relationshipupon a substantially vertical pivot screw |8| which passes through anopening in the upper horizontal portion of the housing |10 and a reduceddiameter lower end thereof is threaded into the lower portion of saidhousing. The pivoted stop members |80 are separated from each other andfrom the housing |10 by respective forwardly extending webs of a spacingmember |82. Referring to Fig. 5, it will be seen that the upper pivotedcolumn selecting stop |80 is positioned in alignment with the path oftravel of the contact portion |43 of the column stopl |40 which isnumbered l, and the remaining column selecting stops |80 are so spacedthat each aligns with the path of travel of the contact portion |43 ofone of the remaining column stops |40 which are respectively numberedfrom two to ve.

All of the column selecting stops |80 may be of identical size and shapeas shown in Fig. 6 wherein it may be seen that each stop |80 is providedwith an extending tail portion |80a which is engaged by a companionexpansion spring |84. The springs |84 are received in respectivehorizontal openings in the guide member |82, and the rearward endsthereof engage a spacing plate |85 secured to the rear vertical portionof the housing |10 as by spot welding.

Referring to Fig. 4, it will be seen that the springs |84 are arrangedfrom bottom to top of the housing |18 at progressively greater distancesfrom the axis of the pivot screw |8| which accordingly results in aprogressively greater effective turning force on the respective stops|80 for purposesy to be later described. As indicated in Fig. 6, thesprings |84 act on their respective stops 180 to normally engage arearwardly projecting lug portion |80b with stop strips |86 which areattached, as by spot welding, to the rear vertical edge of the housing|10.

It will be seen in Fig. 5, that each of the stops |80 is normally heldby its companion spring |84 in a position which is out of the path oftravel of the contact Aportion are individual, rkey actuated,controlling means for operating each of the stops |80 forwardly to aposition where it coacts with the contact portion |43 of the associatedcolumn stop |40.

Referring to Figs. 4 and 5, it will be seen that |43 of the companionvcolumn stop |40. In the present instance, there there is a verticallydisposed actuating lever |90 for each of the stops |88, said levers |90being mounted in spaced parallel relation between the side plates |06and |61 of the case shiftable tabulator frame. The control levers |90are all mounted on a pivot pin 19| which passes through an opening inthe side plate |06 and is provided with a reduced diameter end which isthreaded into the side plate |01. Spacing washers |92 are provided forseparating the actuating levers |90 from each other and for separatingthe end levers from the side plates |66 and |61.

As may be seen in Fig. 5, the upper end portions of the actuating levers|90 which are all substantially U-shaped are received within the housing|10 and extend todiiferent heights so that the upper forwardlyprojecting end of each lever aligns and coacts with only one of thecolumn selecting stops |00.' Referring to Fig. 6, it may be seen thatthe upper engaging end of each of the actuating levers |90 is wedgeshaped to enter a companion one of a series of notches idin thecompanion stop |80.

It will be clear that due to the horizontally spaced arrangement of theupper ends of the levers |90, the upper end of each lever will engagethe companion stop |80 at a relatively different distance from the pivot|8|. Accordingly, the springs |84 are arranged to act on the associatedstops |80`at varying distances from the pivot |8| as previouslydescribed to compensate for the varying effective turning force exertedby each of the levers |90 on the companion stop due to its relativelydifferent point of engagement therewith.

It will be seen from Fig. 6 that each of the column selecting stops isprovided in the forward edge thereof with an engaging notch |80Carranged adjacent to a cam portion |80e and intermediate the contactedges |80e and |80f for purposes which will hereinafter more clearlyappear.

The levers |90, being pivotally mounted on the case shiftable tabulatorframe obviously have a case shifting movement with the stops `|80 alsocarried by said frame, and accordingly means are herein provided foroperatively connecting the lower end of the levers |90 with key operatedkey controlled actuating means mounted on the machine frame regardlessof the case shifted position of the shifting tabulator frame.

The previously me-ntioned bracket (see Fig. 8), which is mounted on theiixed guide plate |48 and accordingly does not have a case shiftingmovement, is provided with rearwardly and downwardlyV extending spacedarms |05a which carry a pivot screw |94 as shown in Figs. 4 and 5. Thepivot |94 passes freely through an opening in one arm |65a and isprovided with a reduced diameter threaded end portion thatis threadedinto a tapped opening in the other arm of the bracket and is retained inplace by a nut |95 threaded on the protruding end of the pivot. There isa bell crank lever |91.fo1` each of the levers |90 mounted on the pivotscrew |94 and retained in spaced parallel relation thereon by spacingwashers |98.

The upwardly extending arm of each of the pivot bell crank levers |91 ispivotally connected at |99 to an associated link 200, which link is inturn connected at 20| to` the lower end of the companion one of theactuating levers |90. The forwardly extending arm of each of the bellcrank levers |91 is pivotally connected at 204 to the upper endigfIacompanion Aoneofgaplurality of substantially `vertically disposedslide members 205. .Each'of thepslide members 205 is provided with yaloQp portion 205a which affords a sli ght resiliency between the pivot204 in the body portion thereof. A contractile spring 206 is connectedto a forwardly extending portion 205b of eachrof the slide membersr205,and the lower ends of all of the springs 200 are connected to ananchoring strip 201 which is hooked around an anchor screw 203which'passes freely through an opening in the vertical web |46 and isthreaded into a tapped opening in the opposite vertical web,|4'|.

Referring to Figs. 1 and 9, it may be seen that the lower end of each ofthe vertical slide members 205 is received in a companion slot in aguidemember 2|0. The guide member 2|0 is mounted by screws.2|| on abracket2|2 which is in turn mounted by screws 2 I3 on the lower crossmember of the machine frame. The slide members 205 are all retained intheir respective slots in the guide member 2 0 by a retaining strip 2|4which is substantially U-shaped to pass around the front edges of allthe members 205 and is attached to the guide member 2|0 by screws V2|5.

Each of the vertically disposed slides 205 is provided with a forwardlyextending toe portion 205c which engages the lower side of a universalarm 2|1 which is pivotally carried at one side by the same pivot |00 andbracket |01 that pivotally carries the crank arm |05. The other side ofthe universal arm 2 I 'l vis pivotally mounted at 2|8 on a dependingbracket 2| 0 which is 4attached at 220 (see Fig. 9) to the centralLportion of the bracket |07. The rearward end of the universal yarm 2|'Iengages the lower side olf the rearward end of the crank arm |05, andaccordingly an upward movement of any one of the slides205 will rock thearm |05 to release the holding dog 92 from the teeth of the escapementwheel 82 in the manner previously described.

In the present instance a key lever operating meansis provided foreffecting a longitudinal upward movement of each of the slide members205. Thus, a key lever arm 225 for each of the slides 205 is pivotallymounted intermediate its ends on a shaft 226 which is retained by screws221 between spaced forwardly eXtending arms 228 carried by the crossmember l1. The extreme rearward end of each of the arms 225 enters thecompanion slot in the guide member 2|0 and an upper rounded edge thereofengages the `lower edge of the companion slide member 205.

Referring to Figs. l and 2, it may be seen that a key lever 230 ispivotally mounted at 23| on each of the arms 225, and the position ofthe levers A230 relative to the companion arms 225 may be adjusted by ascrew 23| threaded through an opening in a horizontally bent portion 232at the forward end of each of the arms 225. The upper end of the screw23| engages the lower edge of the companion lever Y230 to arrest thelever at various positions relative to the companion arm, andtheadjusted position'thereof may be retained by a lock nut -233 threaded onthe screw 23|.

-Theforwardend of each of the key levers 230 extends upwardly asshowninFig. 2 and a stop lug 23.5 is provided which .normally engages ya stopstrip 230 secured to the lower surface ofa guide comb v237 which isattached at its respective end portion at 23.8 to the side plates I0 ofthe-,machine frame. A suitablegkey 240 is secured .to the @Xtremeuppenend .of each `of .thezlevers 230, and each key 240 may .beeprovided with a suitable legend marked thereon such as shown in Fig.V.3.

In -operating the tabulator mechanism ofthe present invention, it willbeclear that a depression of anyone `of theve tabulating keys240 willoperate throughits key levers 230 and;arms .225.to .effect a verticalupward movementof the companion operating slide l.205. movementof theslide 205 releases the carriage for movement fromrighttolefthy releasingthe holding dog 02 from the kteeth of the escapement wheel 82 throughthe luniversal arm 2-|-'| vand crank .arm |05, vas 4previouslydescribed. The upward movement of the slide 205 also operates itscompanion bell crank lever |'91 in a clockwise direction as viewed inFigs. 1 and 5, which in turn operates through its link l200th effect acounter-clockwise operation of the associated pivoted actuatinglever.|90.

The operation of the lever |90rocksthe companion column selecting stop|80 forwardly about the pivot |0| to a position wherein the contactportion |43 of. one ofthe column stops |40, which is at the same levelas the actuated column selecting stop |80, engages the left-.hand wallof the notch |00'C thereof to arrest the carriage in its free movementfrom rightv to left. Referring to Figs. 6 and 8, it will be'seen thatarearwardly extending portion |2aof the guide shoe |02 contacts with theleft-hand surface of the sidefplate |61 and thereby Supports and resistsdisplacement of the frame for the column selecting stops in adirectionof letter space movement upon arrest `of the carriage.

In the operation of the present tabulating mechanism, the carriage asv-it vapproaches the selected position of arrest causes the rear endportion of the contact portion |43 of the column stop |40 to enga-ge theContact edge illf of the companion column selecting stop |80 which is inits forward projected position and thereby exerts va slight cammingactionl thereon and accordinglyfeffects a slight rearward movement ofthe column selecting stopabo-ut itsl-pivot. When the carriage isarrested by the engagement of the contact portion |43 with the left-handwall of the notch |002 the stop member `|80 again moves forwardly ,toits extreme projected position so that the right-hand wall of the notch|80c is in the path of travel of the stop contact |43 in a left-handdirection, and thereby acts to prevent any rebound ofthe carriage from.its arrestedposition.

The previously described slight rearward turning motion of the stopymember |80 as elected by the contact portion |43 in approaching itsarrested `position' may either be allowedby the upward movement of thecompanion tabulating key 2410Jagainst a force exertedrby the operatorthereon, or it may be allowed if ythe operator forcefully retains thetabulating key in its depressed positi-onby a slight compression of theloop portion 205'a of the companion operating slide 205.

It will also be clear that the present tabulating mechanism may beemployed to properly position the carriage when it is manuallyreturnedfrom left to right, during which operation, the contactportion- |43 willengage the sloping-edge I 80e.of the stop |80 to elfectLa-:rearwardmovement ofthe companion stopl'. This rearward movement allowsthecontactportion |43to enter the notch |80cfof thelc-ompanion stop |280and arrest the fright-,hand movement `of the carriage The upward byengaging the' right-hand wall of the notch. In this case, the rearwardmovement of the column selecting stop Ille may also be effected eitherby anr upward movement of the companion tabulating keys 240 or by acompression of the loop portion 205a of the companion slide 25.

Referring to Figs. 3, 5 and 6, it may be seen that the housing llilwhich holds the stop members it@ is provided with a substantially U-shaped cover plate M5 secured thereto by screws 246 threaded into theedge portion of the housing |10. The forward side of the cover plate 2&5is provided with an opening to allow the forward projecting operation ofthe column selecting stops |85). As may be seen, in Fig. 5, the coverplate M5 is provided with a forwardly extending porvtion 24B at theAupper edge thereof, which portion 243, as may be seen in Fig. 3, isbifurcated to form a guide to aid in properly positioning the columnstops ifi@ on the stop bar |25. Thus, the carriage may be manuallyoperated to the desired positionl of arrest for each of the tabulatingkeys, and the associated column stop |40 may then b-e inserted in theinterdental space of the stop bar |25 through the guide formed by thebifurcation in the forward extension 268, thus insuring that thecarria-ge will be arrested at the desired positionupon subsequentoperation of the tabulatingy keys.

An enclosure is also provided for the portion of the present tabulatingmechanism which is mounted between the vertical frame webs Mii and lillby a cover plate 250' which is held in rearward spaced relation theretoby spacing strips 25| which form rearward extensions of the webs |46 andM1 respectively. The cover plate 25B is securedby elongated headedscrews 252 passing through openings therein and through openings in therespective spacing strips 25| and threaded into the webs and |41.

In the present tabulator construction, it will be clear that theactuating levers |90 which are mounted on the tabulator frame for caseshifting movement with the carriage are each connected with thecompanionbell crank lever i il of the key operated mechanism mounted onthe frame `of the machine by respective'links 2M which move during acase shifting operation through a central position which is atrightangles tothe line of case shifting movement of the carriage andtabulator frame. Accordingly, there is no movement of the actuatinglevers |90, or the column selecting stops |80 about their pivots,effected by a case shifting movement of the carria-ge and tabulatorframe relative to the key controlling tabulator mechanism. Furthermore,it will be clear that due to this arrangement of the links 200, the keyoperated controlling mechanism can operate the actuating levers |93 andthe stop I8@ with equal facility regardless of the case shiftedpositions thereof.

It will be seen that I have thus provided an improved, highly efficientand reliable tabulator mechanism and key operated controlling mechanismtherefor in a typewriting machine ofthe type wherein the carriage in itsentirety has a case shifting movement relative to the key operatedcontrolling mechanism. In the specific form shown herein, the tabulatingmechanism is of the column selecting type wherein the column stopsmounted on the carriage have contact portions which are each disposed ata relatively difl ferent position in the line of case shifting movementof the carriage, and accordingly the column selecting stops cooperatingwith the column stops' on the carriage are mounted for a case shiftingmovement therewith in order that the relation between the column stopsand-thecolumn selecting stops will always remain the same irrespectiveof the case positions of the carriage. The key operated controllingmechanism which is mounted on the frame of the machine is operable inthe usual manner to release the carriage for free movement from right toleft, and means have been provided for operating each of the columnselecting stops to a position for arresting the carriage at apredetermined point upon actuation of the vcompanion tabulator key leverregardless of the case shifted position of the carriage and the columnselecting stops which are mounted for case shifting movement therewith.
